Color saliency research on visual perceptual layering method

Abstract

It is a studying worthy problem whether operators can find targets among distractors quickly and correctly with lots of information presented on user interfaces. How to use color saliency properly to optimize interface design is dis-cussed in this paper, according to the guidance of visual perceptual layering. Three laboratory experiments are conducted to assess the anti-interference performances of different colors in three dimensions (hue, brightness and saturation). The an-ti-interference performance is evaluated in reaction time by using a non-parametric statistical test, and the unit of measurement is ΔE76 Euclidean metrics on the perceptually uniform CIE L*a*b*space. The obtained results show that, (1) The pop-out of information effectively can be established by the distance of visual perceptual layering. (2) Visual saliencies of warm colors are different from those of cool colors, and the formers are more salient. High saturated warm colors are more salient than low saturated warm colors, and high bright cool colors are more salient than low bright cool colors. Furthermore, high bright cool colors are less salient than high saturated cool colors. (3) In the hue-contrast condition, with the color difference is more than 20 ΔE76, the visual saliency of target may not change with the change in color differences. Target's saliency is more effected by distractor brightness than by background brightness, whereas it is more effected by back-ground saturation than by distractor saturation. © 2014 Springer International Publishing.
